+The Palliative Treatment of Ingrown Nail+ must necessarily depend upon its original cause. Should it be due to the wearing of improper foot-gear, nothing primarily pathologic in the tissues themselves being present, treatment will be effective only when correct shoes are worn thereafter. Eczematous skin surrounding a nail or infection of a nail groove or matrix, should be treated as such before sufficient hypertrophy takes place to bury the nail edge. The disinfection and drainage of the groove can usually be accomplished with iodin on a thin wire or wooden applicator inserted to the extreme depth of the groove, followed by the insertion of a narrow strip of gauze. Frequent changes of dressings and extreme cleanliness will cause the early subsidence of these infections. It, however, is to be deplored that in the early stages these cases so rarely obtain treatment. Elevation of the nail edge is often practiced quite successfully, but in general, this method of treatment is not applicable to the acute stages of the disease on account of the concomitant pain. Either the nail is too thick to be elevated by the insertion of cotton under its free edge, or the soft tissues are too sensitive to admit of the pressure. The real skill of the chiropodist is called into practice in the treatment of ingrown nail by palliative methods, and he may safely be judged by his results in this class of cases. It requires discrimination whether to attack the exuberant granulation tissue or the cutting nail edge, and in many instances it will be found that both are necessary. Much skill is required in removing that part of the nail which is buried without causing pain or bleeding; this is the first necessity for relieving pain and can only be accomplished by a technic acquired through practice, and often redounding more to the credit of the operator than the successful performance of a major operation. A sharp instrument, usually a chisel, is placed against the free edge of the nail so as to cut only through the nail itself and not into the nail bed, with the purpose in mind of removing a wedge-shaped piece of nail of just the size necessary to relieve irritation, and permit of proper drainage and dressing. Exuberant granulations are best treated either with nitrate of silver applications (50 per cent.) or with tight packing, or both. Disinfection and wick drainage of the entire tract is of the utmost importance. +The Radical Treatment of Ingrown Toe Nail.+ The operations, as in the palliative treatment, naturally fall into two classes depending on (1) whether the nail originally was at fault, or (2) whether the soft tissues, by inflammatory processes, have hypertrophied and overgrown. Operations depending on such diseases or malformations of the nail, causing it to grow down into the tissues, should be directed to the removal of the nail, or the offending part of it with its matrix.
